Conditions: Generalized Anxiety; Worry

Summary: generalized anxiety disorder (gad) is a chronic condition whose hallmark feature is excessive and uncontrollable worry (american psychiatric association, 2013). theories of gad propose that specific cognitive biases are involved in the maintenance and etiology of chronic worry. one cognitive bias that plays a role in worrying is abstract thinking, or the tendency to "verbalize" thoughts and worries in a manner that is vague and lacking in detail. there is evidence that training depressed people to think more concretely improves depressive symptoms and depression-type thinking styles, and reduces emotional reactivity. given that chronic worry and depression have commonalities (e.g., repetitive thinking styles, difficulties with problem-solving and attentional control, emotion dysregulation), concreteness training may help people who struggle with chronic worry. the main goals of this proof of concept experiment are 1) to test in individuals reporting chronic worry the effects of an active form of concreteness training that involves imagery practice (compared to a no training control condition) on frequency of worrying, problem solving quality, and worry-related processes; 2) to examine the degree to which concreteness training causes improvements in daily worry and negative affect during the 7 days of practice. the study design will provide us with an understanding on a more "macro" level of the potential short-term benefits and will at the same time allow us to see, on a more "micro" level, how training concreteness affects worry and mood on a day-to-day basis during a 7-day period. the findings from this study will inform relevant clinical literature about efficacious methods to reduce chronic worry.

the main goals of this proof of concept experiment are 1) to test in individuals reporting chronic worry the effects of an active form of concreteness training that involves imagery practice (compared to a no training control condition) on frequency of worrying, problem solving quality, and worry-related processes; 2) to examine the degree to which concreteness training causes improvements in daily worry and negative affect during the 7 days of practice. participants are recruited from the community via advertisements. following a telephone screen, participants attend a baseline visit during which they complete the mini interview. those who continue to be eligible complete the outcome measures and are randomly assigned to either the experimental condition or the control condition. participants assigned to the experimental condition receive training in concrete processing and learn how to complete the daily experience sampling diary. participants assigned to the control condition do not receive training and learn how to complete the daily experience sampling diary. all participants then complete their assigned activities for 7 days. they then return to the lab to complete the outcome measures at post-test, 1 week follow up and 1 month follow up. participants are then debriefed.

Eligibility criteria:
inclusion: 1. penn state worry questionnaire (trait) score meeting threshold of 65 or higher. 2. endorsement of symptoms consistent with generalized anxiety disorder on the mini interview with a csr equal to or greater than 4. 3. if other symptoms are present, associated csr is at least 1 point lower than the csr associated with gad symptoms exclusion 1. having a current or past history of mania or psychosis, or endorsement of symptoms consistent with a substance use disorder in the past 12 months. 2. reporting of suicidal ideation, intent or plan. 3. participants are excluded if they are currently receiving psychological treatment or counseling unless this treatment is infrequent (meeting once monthly or less) or the participant has been receiving consistent weekly treatment for 12 weeks and still meets all other eligibility criteria. 4. psychotropic medication with a change in dose in the past 12 weeks. if they have recently discontinued a psychotropic medication, they will be included if it has been at least 1 month since discontinuation or 3 months in the case of fluoxetine.
